A Cyber Attack Mitigation Scheme for Series Compensated DFIG-Based Wind Parks

Subsynchronous Interaction (SSI) phenomenon is known to be one of the most frequent and severe stability issues a Wind Park (WP), can potentially lead significant loss power generation. The broad impacts this on grid have made WPs interesting targets for cyber attacks. To initiate SSI, an adversary target either (external attacks) or system (internal attacks). This paper proposes mitigation scheme attacks that SSI in series compensated doubly-fed induction generator (DFIG)-based WPs. External are addressed by employing robust static-output-feedback Damping Controller (SSDC), which designed based insensitive strip region Linear Matrix Inequality (LMI) techniques. Internal attacks, however, detected comparing estimated measured converters’ currents. Once compromised measurements detected, SSDC restructured mitigate effectiveness proposed method demonstrated using detailed Electromagnetic Transient (EMT) simulations both internal external Additionally, performance corroborated real-time co-simulation framework.
